Improvement in sash-holders



PATENT FFIUE.

HANSON P. TENANT, OF EAST GERMANTOWN, INDIANA.

IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent N 0. 124,640, dated March 12, 1872.

To'dll whom it may concern:

Be it known that I, H. P. TENANT, of East Germantown, in the county of Wayne and State of Indiana, have invented an Improved Sash-Look; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which 7 Figure 1 is a perspective view. Fig. 2 is a longitudinal vertical section, showing both the top and bottom lock, the sash being represented as looked down. Fig. 3 is a similar section, showing the sash locked up; and Fig. 4 is a similar section, showing the position of the parts while the sash is being raised or lowered from one look to the other.

Similar letters of reference in the accompanyin g drawing denote the same parts.

The object of this invention is to provide for public use a simple, cheap, convenient, and effective self-operating sash-lock, which can be used in connection with any form of sliding sash-for windows or other similar purpose 5 and to this end the invention consists in the im proved construction and arrangement of all the parts constituting the lock, substantially as hereinafter set forth.

' In the drawing, A is the sash, and B the window-frame, provided with moldings b b to hold and guide the sash. O is an oblong metal plate, conntersunk'in the frame, to which it is secured by screws, as shown. A deep horizontal groove, m, extends from the inner edge of the plate nearly to the opposite edge, but instead of extending quite across terminates in a hole or socket under the surface of the plate, which receives and supports one end of a double crank-shaped rod, D. The opposite end of said rod passes under the molding b, which holds it in place, and then, bending forward, extends out through a vertical slot, 8, in said molding, and terminates in a small weight, w, which operates to hold the crankshaped rod in the position represented in Fig. 1. A rectangular groove, n, is also formed in the face of the plate, as shown, to receive the bent part of the rod when the adjusting of the sash forces its lock out of the way, or when the weighted arm to is lifted for the purpose of unlocking the sash and letting it down or up. In order to facilitate the attachment of the several parts the slot 8 is made open at the inner side of the molding b, and after the rod D has been properly adjusted a small neat metal plate, 6,

is fastened upon the molding so as to conceal the side opening and prevent dirt and water from lodging therein, and, at the same time, to cover the edges of the slot on the front side of the molding around the arm and weight w and render the appearance of the whole neat and ornamental. The sash is constructed with two recesses in its outer edge, one, 1', near its lower end, and the other, 1", near its upper end, the section of both being an acute triangle with the base up, as shown in Figs. 2 and 3. As the sash is raised or lowered it pushes back the Wire D into the recess a, as shown in Fig. 4, until the recess a" or 1" comes in front of it, when the weight w causes the bent part of the wire to drop forward into said recess in the sash and hold the'latter up, as represented in Fig. 3, or look it down, as represented in Fig. 2 To prevent the wire from wearing into the Wood in consequence of the weight of the sash, I line ,the upper part of the lower recess 1" with metal, as shown at c,- and to enable the loop of the wire to lock the sash down securely, I fasten in the upper part of the recess 1" a metal catch, 0, constructed in the form clear] y shown in Fig. 2, over which the loop passes whenever the sash descends to the proper posit-ion.

By raising the arm n the device can be readily unlocked from within the house, but there are no means of operating it from the outside.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

The self-operatin g sash-lock herein described, consisting essentially of the plate 0 constructed with the grooves m n, as shown, the bent rod or wire D, the weighted arm w, and the recesses r r in the sash, provided, respectively, with the metal catch 0 and the metal plate c, all arranged as specified, and operating to lock the sash down or up, as herein set forth.
